(c-mode-base-map, c++-mode-map):

(c-mode-base-map, c++-mode-map):
Move `/' as an electric character
from c++-mode-map to c-mode-base-map for all languages.

(c-common-init): Set comment-multi-line and
comment-line-break-function here for all modes.
Make comment-line-break-function buffer local iff it's boundp.

(c-C-comment-start-regexp): Obsolete.

(c-comment-start-regexp): Initialize from c-C++-comment-start-regexp.

(c-populate-syntax-table, c-setup-dual-comments): Merge both functions
into c-populate-syntax-table.  With the new 9X draft C standard, both
line and block oriented comments are supported in all modes, so always
set up the syntax tables to support both comment styles.

(c-enable-//-in-c-mode): Obsolete.

(c++-mode-syntax-table, java-mode-syntax-table)
(objc-mode-syntax-table, idl-mode-syntax-table): Added autoload
cookies.  c-mode-syntax-table already has one.  Use the new syntax
table initialization idioms.
